1 TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA7358P FM Front End The TA7358P is designed for a FM front end application, which is suitable to a portable radio or a radio cassette. Comparing with conventional types, supply voltage dependence, overload characteristics and spuious radiation characteristics are improved. Features Wide supply voltage range : VCC = 1.6~6.0V Excellent supply voltage dependence of local oscillator : Oscillation stop VCC = 0.9V (typ.) Improved inter modulation characteristics by double balanced type mixer circuit. Low spurious radiation. Build in clampping diode for the local oscillator output. Weight: 0.92g (typ.) Block Diagam 1
